Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583296, here are decompositions:

137 + 31583159 = 31583296
149 + 31583147 = 31583296
263 + 31583033 = 31583296
347 + 31582949 = 31583296
359 + 31582937 = 31583296
383 + 31582913 = 31583296
389 + 31582907 = 31583296
449 + 31582847 = 31583296

Showing the first eight; more decompositions exist.
